The trophic cascade theory (CARPENTER er al. 1985, 1987) has been applied to a number
of field and experimenral studies on biomanipulation (eg DRENNER er al. 1987, PosT & …

Silver carp, Hypophthalmichthys molitrix (Val.), feeds on both phyto‐and zooplankton and
has been used in lake biomanipulation studies to suppress algal biomass. Because reports …

Manipulative food web experiments in mesocosms (eg, enclosures, tanks) and whole-lake
manipulations are now widely used to explore biotic and nutrient-mediated interactions …

A factorial study conducted in large enclosures (8 m dia x 14 m deep) was used to assess
the relative impacts of fish (1+ yellow perch) and nutrients (nitrogen and phosphorus) on …

The possibility to use silver carp (Hypophthalmichthys molitrix) in the control of water
blooming by cyanobacteria is theoretically analyzed. To attain this goal the dynamic model …

Deliberate trophic-level manipulations have recendy been carried out to test their ability to
reduce algal abundance in ponds and lakes (STENsoN et al. 1978; LYNCH & SHAi> IRO …

Biomanipulation (as defined by Shapiro) and top-down or consumer controlled forces refer
to the control of natural aquatic organisms to improve water quality instead of through …

Reduction of excessive external phosphorus loading is the first measure in the management
of eutrophic lakes (eg SAS 1989). Due to the well-known effects of dense cyprinid …

Results from long-term investigations on biomanipulation show that indirect effects are at
least as important as direct effects are for the stability of biomanipulation. Three types of …

When silver carp were introduced into the Netofa reservoirs at an initial density of 300–4500
fish per hectare in order to control phytoplankton and zooplankton, there was a significant …
